I've got 5 4x8 beds of king stropharia and 2 mounds, growing 2 types of oyster mushrooms. last summer i got ALOT of mushrooms! i dried a lot and gave some to friends. they aren't as hard as you think to grow if you let mother nature do it for you. i started that spring w/ one bed of hardwood sawdust 2 yrs ago. i bought a bag of sawdust spawn form mushroom mountain for $25. broke it up in small pieces and mixed into 6in. of sawdust. covered with a 6in. layer of straw. kept that moist till next spring. by then the sawdust was completely colonized and white w/ mycelium. instead of letting them fruit, i dug up the bed and divided it between 4 other beds of sawdust. last june those beds all produced probably 30 lbs. of mushrooms total. i also started oysters at the same time. i bought 2 packages of oyster hardwood plugs. instead of putting them in logs i mixed them into 2 2ft tall sawdust piles under my spruces and covered w/ straw and kept moist. probably got 10lbs out of them. everything is planted under my big norway spruces which give great shade. this spring I'm going to mix in some more sawdust into the beds and piles to reinvigorate them. maybe try a few different varieties. i have a firewood business down the road that i get a unlimited supply of fresh hardwood sawdust for free. a mix of maple, birch and beech which is perfect for these species. if you can plant a garden you can do this!
